The synthesis of various substituted 1H-indazoles is reported through N-N bond formation from an iminophosphorane derivative. Supported by control experiments, an original Staudinger-aza-Wittig tandem mechanism is proposed for this transformation.

Thermolysis of 2-azidophenyl ketoximes provides 2-hydroxyindazoles, which in aqueous salution usually exist in the alternative 1H-indazole 2-oxide tautomeric forms.Both N- and O-substituted derivatives are produced on alkylation.
